BIG PICTURE -­ What are genes? Sequence of bases that codes for the production of 1 protein -­ What is mRNA? mRNA is a single stranded copy of a gene -­ What are amino acids? How are amino acids made? Amino acids make up proteins. They are identified by tRNA based on the sequence of bases on the anti codon. -­ What are proteins? What do proteins do? Proteins are chains of amino acids. Proteins are vitally important molecules that enable organisms to carry out the BIG 7. -­What are traits? Traits are characteristics or features of an organism -­ How do Genes become Traits? Genes code for proteins. Proteins then complete the structure of an organism and control all of the chemical functions in an organism, which are the traits of an organism. Genes contain information to make proteins, and those proteins create the traits in an organism. RNA
DNA
- Single Strand
- Uses Uracil instead of
Thymine
- Uses Ribose instead of
Deoxyribose
- Double Strand
- Uses Thymine
- Uses Deoxyribose
Type of RNA
Job
mRNA
Copy the information about how to make a single
protein in a gene into a single mRNA strand
tRNA
Bring the correct amino acid to the
ribosome
rRNA
Part of the ribosome that reads the mRNA
